John Bruno, a Lockport resident, was at the courthouse, 16501 S. Kedzie Pkwy., on Sept. 21, 2007 when he intended to re-holster his weapon, according to a suit filed in Cook County Circuit Court.

As he attempted to put the gun back into the holster, the weapon unexpectedly discharged, the suit said.

Bruno is suing Bushnell Outdoor Products, Michael’s of Oregon, Co., Uncle Mike’s and Kale Uniforms, Inc.—the companies that manufacture and sell the Kydex Belt Holster for Glock Model handguns—claiming the product was defective and caused him to shoot himself.

The suit claims the holster’s retention strap moved out of position when a weapon is being re-holstered, which causes the gun to discharge and, in Bruno’s case, caused him “severe” and “permanent” injuries.

It was unclear why Bruno had a weapon at the courthouse, and his lawyer could not immediately be reached for comment Wednesday evening.
